Best practise vue.js frontend and python backend
问题
我想要一个Python脚本来触发Vue.js组件的点击事件。大多数我见过的方法似乎通过一个.json文件进行数据交换。前端中的事件不直接进入脚本，而是更新了所使用组件的属性的.json文件。Python读取该文件并将其推送回去。
因为我对涉及Vue.js的一切都很陌生，所以我想问一下最佳实践是什么。还有一些建议，比如使用FastAPI、Django或Flask，然后让Vue.js进行渲染！
提前感谢。
英文:
I want a python script to trigger on-click events of vue.js components.
Most ways I've seen, seem to work by a .json for data exchange. Events in the frontend are not directly into script, but update a .json with properties of the used components.
Python reads the file and pushes it back.
Since I'm new into everything which involves vue.js, I want to ask what best practise is. Since there also suggestion like going with FastAPI, Django or FLask and let vue.js do the rendering.!
Thanks in advance.

Vue.js是一个很棒的学习语言，很高兴你正在学习它！
有几种方法可以将Python与Vue集成，你的Python后端确实可以通过操作JSON数据来工作。然后，你的Vue.js应用程序将根据用户操作（例如点击事件）触发API请求（GET、POST等）到Python后端。
让我们以Python Flask为例进行说明。我们可以创建一个基本的API，当命中特定路由时简单地返回一些数据：
from flask import Flask, jsonify
app = Flask(__name__)
@app.route('/api/data', methods=['GET'])
def get_data():
data = {'key': 'value'}
return jsonify(data)
if __name__ == '__main__':
app.run(debug=True)
然后，在你的Vue应用程序中，你可以使用像axios这样的HTTP客户端在按钮点击时发送GET请求到这个路由，并对响应数据执行操作。
安装Axios：
npm install axios
Vue.js：
<template>
<button @click="fetchData">Fetch data</button>
</template>
<script>
import axios from 'axios';
export default {
methods: {
fetchData() {
axios.get('http://localhost:5000/api/data')
.then(response => {
console.log(response.data);
// 对response.data执行操作
})
.catch(error => {
console.error(error);
});
}
}
}
</script>
这样，当这个Vue.js组件中的按钮被点击时，它将触发一个GET请求到http://localhost:5000/api/data（Flask服务器），并记录响应数据。
这只是一个简单的示例。在真实的应用程序中，你可能希望正确处理错误，并可能使用Vuex来管理你的应用程序状态。

Vue.js is a great language to learn, glad you are picking it up!
There are a few ways to integrate Python with Vue, your Python backend could indeed work by manipulating JSON data. Your Vue.js application would then trigger API requests (GET, POST, etc.) to your Python backend in response to user actions, like click events.
Let's take an example with Python Flask. We can create a basic API that simply returns some data when a specific route is hit:
from flask import Flask, jsonify
app = Flask(__name__)
@app.route('/api/data', methods=['GET'])
def get_data():
data = {'key': 'value'}
return jsonify(data)
if __name__ == '__main__':
app.run(debug=True)
Then in your Vue app, you would use an HTTP client like axios to send a GET request to this route when a button is clicked and do something with the response data.
Install Axios:
npm install axios
Vue.js:
<template>
<button @click="fetchData">Fetch data</button>
</template>
<script>
import axios from 'axios';
export default {
methods: {
fetchData() {
axios.get('http://localhost:5000/api/data')
.then(response => {
console.log(response.data);
// do something with response.data
})
.catch(error => {
console.error(error);
});
}
}
}
</script>
This way, when the button in this Vue.js component is clicked, it will trigger a GET request to http://localhost:5000/api/data (the Flask server) and log the response data.
This is a simple example. In a real-world application, you'd want to handle errors properly and probably use Vuex to manage your application's state.
